According to this report by Jason La Canfora, recently released Browns linebacker D'Qwell Jackson has visits lined up with the Titans and Broncos. But in that same article, Jason La Canfora mentions that the Vikings are also reportedly interested in Jackson.

The Browns released Jackson right before he was set to earn a $4 Million roster bonus, and the 30-year old linebacker (who will turn 31 right at the start of the season) is now a free agent and ready to sign with any team.
